A mobile communication device includes a first plate, and a second plate provided with guide rails on respective edges thereof and slidably coupled to the first plate. A main body is coupled to the first plate and a sub body is coupled to the second plate. Torsion springs are provided on the first plate, adjacent to respective edges of the first plate. Contact members are respectively provided at one end of each torsion spring and each contact member contacts a corresponding guide rail due to elasticity of the torsion spring. Guide slits are disposed in the first plate, adjacent to respective edges of the first plate. Each guide slit receives a corresponding contact member.

A semi-automatic swing device for a swing-type portable terminal. The semi-automatic swing device includes a first member; a second member for semi-automatically performing first and second swing operations along a desired trajectory on the first member, while facing the first member; guide means having a first guide portion formed in the first member and a second guide portion spaced apart from the first guide portion, for determining a direction of the swing operations; a driving source installed in the first guide portion, for allowing the second member to semi-automatically perform the swing operations; and first and second coupling members mounted on the second member and coupled with the first and second guide portions, respectively, the first and second coupling members moving along the first and second guide members and restricting the first and second members while the first and second members face each other.

Disclosed is a camera lens assembly of a portable terminal, which includes a lens housing; and a drive plate provided at a position adjacent to the lens housing, wherein the lens housing rotates as the drive plate moves linearly. Because of the camera lens assembly, the lens housing need not be directly manipulated to rotate the lens housing. Therefore, since the lens housing is installed in the housing of the terminal, even in a state in which the lens housing is rotatably installed on the housing of the terminal, damage and breakage due to exterior impacts can be prevented and the restrictive terminal design problem due to the lens housing is overcome.

Camera lens assembly for portable terminal

Disclosed is a battery pack locking device for a mobile phone which attaches or detaches the battery pack to or from a body of the phone by slidably moving a cover of a camera lens module. The battery pack locking device includes a sliding cover; a push locker portion moved upwardly or downwardly according to movement of the sliding cover; a slide locker portion slidably moved according to the upward or downward movement of the push locker portion to restrict or release the battery pack; and a resilient member.

A slide module of a slide type portable terminal which constitutes a slim slide module in a slide type housing and a cover apparatus for an external type card mounted to the slide module are disclosed. A slide module of a slide type portable terminal having a body housing and a slide housing for opening and closing the body housing when slid includes: a guide member; a slide member receiving the guide member in an inner side thereof in an opposed manner and engaged with both sides of the guide member so as to slide; and a force providing means provided between the members, for providing a force to slidably move the slide member.

Slide module for slide type portable terminal and cover apparatus for external type card mounted thereto

Disclosed is a pop-up type portable terminal. The pop-up type portable terminal includes a main housing, a sub-housing slidably coupled to the main housing such that the sub-housing is slidably accommodated in or withdrawn from the main housing, a main board installed in the main housing, a guide beam fixed to one side of the main board and extending lengthwise along the main board, a guide rail installed at a rear surface of the sub-housing and extending lengthwise along the sub-housing so as to engage with the guide beam for guiding a sliding movement of the sub-housing, and a torsion coil spring installed in the main housing and having a first end portion fixedly coupled to the main housing and a second end portion fixedly coupled to the sub-housing in order to provide bias force in a direction urging the sub-housing to be withdrawn from the main housing. Noise caused by friction between the guide beam and the guide rail is thereby significantly reduced.

Pop-up type portable terminal

A portable terminal is disclosed having a first housing; a swing hinge module providing a rotation axis which extends perpendicularly to a top surface of the first housing; and a second housing coupled to the swing hinge module and adapted to be rotated about the rotation axis while facing the first housing. As the second housing is rotated about the rotation axis, the swing hinge module stops the rotation of the second housing at least once at a predetermined position. The second housing is rotated semi-automatically by means of the swing hinge module.

Portable terminal and swing hinge module thereof

Disclosed is a serration apparatus for a portable terminal mounted in a camera lens module of the portable terminal having a serration module. The serration apparatus includes a first serration gearing; a second serration gearing mounted on the camera lens module and receiving and compressively meshing with the first serration gearing within its inner side, wherein when the camera lens module is rotated, the second serration gearing is rotated with the camera lens module and produces frictional force against the first serration gearing, thereby creating a clicking feeling; and an elastic member for providing compressing force to cause the first and second gearings to be meshed with each other.

Serration apparatus for portable terminal

The present invention relates to a handheld radiotelephone having a battery pack attachably and detachably equipped on a rear surface of a main body, and a locking device for allowing the battery pack to be attached or detached.
